1 前言
導航欄標題不一定非要是文字，可以是圖片，甚至是任何視圖控件，今天我們就來另行其道，用UIImageView來作為導航欄的title。

2 實例代碼
ZYViewController.m代碼：

[plain]
- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
    self.view.backgroundColor = [UIColor whiteColor]; 
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 40.0f)];//初始化圖片視圖控件 
    imageView.contentMode = UIViewContentModeScaleAspectFit;//設置內容樣式,通過保持長寬比縮放內容適應視圖的大小,任何剩余的區域的視圖的界限是透明的。 
    UIImage *image = [UIImage imageNamed:@"titleView.png"];//初始化圖像視圖 
    [imageView setImage:image]; 
    self.navigationItem.titleView = imageView;//設置導航欄的titleView為imageView 
} 

- (void)viewDidLoad
{
    [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
    self.view.backgroundColor = [UIColor whiteColor];
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 40.0f)];//初始化圖片視圖控件
    imageView.contentMode = UIViewContentModeScaleAspectFit;//設置內容樣式,通過保持長寬比縮放內容適應視圖的大小,任何剩余的區域的視圖的界限是透明的。
    UIImage *image = [UIImage imageNamed:@"titleView.png"];//初始化圖像視圖
    [imageView setImage:image];
    self.navigationItem.titleView = imageView;//設置導航欄的titleView為imageView
}
